Which number is an integer?

-3/4

1/5

2

4 2/3

2 is an integer.

Choice c

Answer: C. 2

An integer is one that isn't a fraction or a decimal.

-3/4 is a fraction, which converts to - 0.75

1/5 is also a fraction and it is equal to 0.2

This is why we can rule out choices A and B. Choice D is a similar story.

Put another way, an integer is a whole number that is used to count people, places, things, etc.

Note: choice D is a mixed number consisting of a whole part (4) and a fractional part (2/3). This converts to the improper fraction 14/3, and that converts to the approximate decimal form of 4.67
